Rapidex
The RapidexTM is designed with marine propeller blades that provide cavitation-free operation while delivering intense agitation. The smooth finish and shape of the RapidexTM impeller blade make it very suitable for sanitary applications. The RapidexTM operates at a low tip speed, consumes little energy and is available in different diameters from 110mm – 800m. Although this type of mixer is often used in storage tanks for circulation, they are extremely energy inefficient for this purpose.

RAPIDEX
This type of mixer has limited dispersing capacities due to the small shear surface, but is widely applicable for “simple” mixing or soluble ingredients. RapidexTM provides intense low shear agitation, even at a viscosity of up to 25,000 cp. The RapidexTM is mainly used in the food, beverage, cosmetics, pharmaceutical and chemical industries to stir or mix liquids

Energy saving
Larger impeller diameter = Lower top speed = lower power consumption:
The power consumption of a mixing impeller is the result of the following parameters:
- viscosity and specifications of the mixture.
- diameter, speed and power number of the impeller.

Admix ensures that the drive shafts have a shaft diameter and finish that match the application. In addition, they may have a maximum tolerance of 0.1 mm to pass the Admix quality control. This ensures more stable operation, less vibration, more safety and reduces wear.
The RapidexTM blade is designed to move liquids quickly without creating turbulence. This ensures high fluid circulation and low energy consumption. The propeller is designed from shaft to tip in such a way that oblique turbulence is avoided: Not just at the back of the blade but over the entire blade length. This reduces the chance of air being drawn into the product.
Do you have a mixing problem? Let Admix create a custom solution for you. Our experienced application experts are ready to work with you to find a solution for your application based on your viscosity, densities, ingredients and batch sizes. This guarantees you a solution that does what you expect it to do the first time.
